Abstract
We study the relationship between climate change social norms (CCSN) and corporate cash holdings for U.S. firms. We find that county-level CCSN is significantly positively associated with cash holdings. Our main finding is robust to a battery of robustness tests. In a subsample analysis, we find that firms have relatively low cash holdings in low CCSN counties even when faced with high climate risk. For such firms, the lack of cash buffer could be harmful to a broader set of stakeholders faced with heightened climate risk. We also show that cash holdings are a potential mechanism through which CCSN influences future environmental corporate social responsibility (CSR) performance. Overall, our study suggests that county-level CCSN has significant implications for corporate cash holdings.

Notes
Consistent with prior literature (e.g., Bates et al., 2009), cash accounts for roughly 26% of the total corporate assets in our sample.
We describe the construction of CCSN in detail in "Measure of Climate Change Social Norms" section.
Even if reverse causality is less likely to be a concern, we still conduct a test reported in the additional robustness tests in "Additional Robustness Tests" section to further eliminate this concern.
Consistent with this view, Arouri and Pijourlet (2017) propose a “conflict-resolution” view stating that firms engaging in CSR are more likely to hold cash in the interests of shareholders.
A central theme regarding climate change is the costs and benefits associated with climate change. Ethical issues arise when there is an attempt to address who should pay for climate adaptation and mitigation efforts (Grasso and Markowitz, 2015).
One concern is that Compustat does not report firms’ historical headquarter locations. However, according to Pirinsky and Wang (2006), less than 3% of firms changed their headquarter locations over the period from 1988 to 2002. Given the shorter time span of our data (i.e., 2014–2020), corporate headquarter relocation is therefore unlikely to be a concern for our study.
Please see “Appendix” for definitions of Happening, HarmUS, and Worried.
Our findings remain qualitatively unchanged when standard errors are clustered at the firm level, as reported in "Additional Robustness Tests" section.
It is worthwhile to note that untabulated results suggest that CCSN has not only a cross-sectional variation but also a temporal variation. Generally, there is an increasing trend in CCSN from 2014 to 2020. For instance, the proportion of respondents residing in Alabama who are concerned about global warming increased from approximately 46–56% over the sample period.
We also check the variance inflation factor (VIF) for each variable and find that none of the VIFs exceed 5, mitigating the concern of multicollinearity.
For the sake of brevity, the coefficients on the indicator variables on industry and year are not reported. Our results are qualitatively similar in the robustness tests when using Cash-to-assets and Cash-to-net assets as alternative dependent variables.
Hurricane Maria is not considered here because it did not hit the U.S. mainland in 2017.
See https://www.fema.gov/disaster for more details.
We acknowledge that the exclusion criterion is not mathematically testable. However, it is plausible that political climate may influence CCSN through other channels such as tax laws. Therefore, certain caution should be exercised when interpreting these results (Baldauf et al., 2020).
The data is sourced from https://www.c2es.org/document/climate-action-plans/.
A state is considered a Democratic state if it was won by a Democratic presidential candidate in 2 of 3 presidential elections in 2008, 2012, and 2016; otherwise, we treat it as a Republican state.
Former U.S. President Trump made the statement regarding the withdrawal of the U.S. from the Paris Agreement on June, 1, 2017 (see https://www.nytimes.com/2017/06/01/climate/trump-paris-climate-agreement.html for more details).
The dominant political view depends on the state-level presidential elections data in 2008, 2012, and 2016. Note that we don’t use the 2020 presidential election data because it is usually deemed controversial. Our results continue to hold when we use four or five years of election results (i.e., 2000, 2004, 2008, 2012, and 2016).
We thank an anonymous reviewer for raising this point.
A potential drawback of this approach is that the electric vehicle data is cumulative and only available for 2020, which significantly reduces the sample size.
We construct a state-level behavior-based CCSN, because responses to the question “Hear about global warming in the media at least once a week” are unavailable for 2016.
Our results continue to hold if we employ a scaled decile-ranked variable.
To conserve space, the cross-sectional analyses results are untabulated but available from the authors upon request.
The formulas to calculate both the WW and HP indexes are listed in “Appendix”.
These data are drawn from https://osf.io/fd6jq/.
Relatedly, we also investigate the sources of cash holdings and we document that firms that are located in high-CCSN counties reduce their dividend payment, have a reduced likelihood to pay a dividend, and cut back net working capital and capital expenditures. We also rule out competing explanations of increased cash holdings by ruling out the tax motive, the role of R&D investment, the effect of manufacturing firms, and the agency motive. These results are unreported in the text given the space constraint but available upon request from the authors.
The path coefficients are the standardized coefficients generated by path analysis automatically.
Untabulated results show that the impact of CCSN on future CSR environmental performance continues to hold up to three years in the future period.
